The sound quality is excellent, whether it is listening to Haydn via CD

Quality in normal listening is outstanding

Awesome sound quality!

Not just BOOM, but actual quality!!

Excellent quality

But this one was perfect it's but the quality is superb

Very poor quality sound (little separation between notes, heaps of port noise, muffled...).

But for now -- this well built, powerful, high quality beast is as good as my old Velodine sub.
